Liquid detergent composition for hard surfaces

Abstract

Provided is a liquid detergent composition for hard surfaces which contains (a1) an amine oxide-type surfactant having at least one alkyl group or alkenyl group with 13 or more and 18 or less carbons [hereinafter, referred to as component (a1)]; and (b1) a sorbitan fatty acid ester in which the fatty acid residue has 10 or more and 18 or less carbons [hereinafter, referred to as component (b1)]; and water, wherein the mass ratio of the content of component (a1) to the content of component (b1), (a1)/(b1), is 0.4 or more.Also provided is a liquid detergent composition for hard surfaces which contains a surfactant in an amount of 0.1% by mass or more and 20% by mass or less; and water, wherein the liquid detergent composition contains, as the surfactant, (a2) an amine oxide-type surfactant having at least one alkyl group or alkenyl group with 7 or more and 12 or less carbons [hereinafter, referred to as component (a2)] and (b2) a glycerin fatty acid ester in which the fatty acid residue has 10 or more and 18 or less carbons [hereinafter, referred to as component (b2)], and wherein in the surfactant, the total content of the content of component (a2) and the content of component (b2) is 40% by mass or more.

1 . A liquid detergent composition for hard surfaces, comprising: (a1) an amine oxide-type surfactant having at least one alkyl group or alkenyl group with 13 or more and 18 or less carbons [hereinafter, referred to as a component (a1)]; and (b1) a sorbitan fatty acid ester in which the fatty acid residue has 10 or more and 18 or less carbons [hereinafter, referred to as a component (b1)]; and water, wherein
 a mass ratio of the content of the component (a1) to the content of the component (b1), (a1)/(b1), is 0.4 or more.   
     
     
         2 . The liquid detergent composition for hard surfaces according to  claim 1 , wherein the mass ratio of the content of the component (a1) to the content of the component (b1), (a1)/(b1), is 0.7 or more and 20 or less. 
     
     
         3 . The liquid detergent composition for hard surfaces according to  claim 1 , wherein the total content of the content of the component (a1) and the content of the component (b1) is 0.02% by mass or more and 40% by mass or less. 
     
     
         4 . The liquid detergent composition for hard surfaces according to  claim 1 , wherein the number of carbons in the fatty acid residue of the component (b1) is 18. 
     
     
         5 . The liquid detergent composition for hard surfaces according to  claim 1 , wherein a content of a surfactant other than the component (a1) and the component (b1) is less than 5% by mass. 
     
     
         6 . The liquid detergent composition for hard surfaces according to  claim 1 , wherein the liquid detergent composition for hard surfaces has a pH of 5 or more and 9 or less at 25° C. 
     
     
         7 . The liquid detergent composition for hard surfaces according to  claim 1 , wherein the liquid detergent composition for hard surfaces is intended for a food processing installation or a cooking installation. 
     
     
         8 . A method for cleaning a hard surface in which the detergent composition according to  claim 1  is contacted with a hard surface stained with oil spots including a degenerated oil.
